The following scenarios describe the steps for failing over PPRC in order to move workload from the primary to the recovery site, and subsequently failing back when returning processing to the primary site. For failover/failback scenarios in a Global Mirror configuration, see Failover/failback for a Global Mirror session. For failover/failback scenarios in a Metro/Global Mirror configuration, see Metro/Global Mirror recovery scenarios.
In these discussions, the volumes at the primary (home) site are referred to as the A volumes, and the volumes at the recovery site are referred to as the B volumes. FlashCopy® volumes are referred to as C volumes.
